AssetBundle.LoadFromFile加载一个80MB的assetbundle会分配1MB左右的pss内存

adb分析：private-other
UnityProfiler分析：有3块
1.Other/AssetBundle/LoadingCache 
2.Other/SerializedFile/archive:/CAB-e42axxxxxxx
3.NotSaved/AssetBundle/xxxxxx.ab

ab.LoadAllAssets或ab.LoadAsset会从磁盘上加载具体的资源到内存中约110MB
adb分析：根据不同的手机有不同的情况
中兴a2322有两块：1.graphics，2.private-other
OPPO k10有一块 private-other
UnityProfiler分析：为主要为一块即Assets/下面的具体资源，
如果有ParticleSystem，prefab，等其它资源的的话也会有其它的内存如：SceneMemory/ParticleSystem,SceneMemory/GameObject等等

ab.Unload(true)后
adb分析：会根据操作系统决定释放多少内存，或者不释放。
UnityProfiler分析：会释放掉绝大多数的资源，比如他可能并不释放Other/AssetBundle/LoadingCache这一块
